Clutches....
« on: September 18, 2008, 07:52:58 pm »
will the clutch out of my 79 with a 350/sm465 work if i replace the 350 with a 400 or do i need a different one? The clutch that is in there is fairly new and i dont wanna have to buy a new one unless i have to.

Clutch will all work but I believe the flywheel for a SB 400 needs to be externally balanced from what I remember.
